If Victorians were offended by Charles Darwin's claim that we descended from monkeys, imagine their surprise if they heard that our first ancestor was much more primitive than that, a mere single-celled creature, our microbial Eve.

Trial and error, experimentation, the understanding that some questions have complex answers or no answers at all, the notion that failure teaches, the acceptance that mistakes can actually guide you in the right direction, persistence in the face of difficulty: These are some of the everyday components of scientific research, accumulated wisdom that can serve us well in many walks of life — from how to face challenges as individuals to running corporations.

Last week, my 13.7 co-blogger Tania Lombrozo reported on a study she developed with graduate student Sara Gottlieb on whether science can explain the human mind.

As Tania wrote, this was a survey-based study asking the participants "whether they thought it was possible for science to one day fully explain various aspects of the human mind, from depth perception and memory loss to spirituality and romantic love."

For this post-Thanksgiving week, I'd like to suggest a remarkable video produced over two decades by NASA scientists.

Satellites monitored populations of plant life on land and oceans, mapping variations of green regions of vegetation and snow cover on the North and South Poles. As seasons pass, we witness a rhythmic dance between white and green, as if the planet itself were breathing.

"It is not about you," says the Ancient One, marvelously played by Tilda Swinton in the movie Doctor Strange — based on the Marvel comic — released in theaters last Friday.

She is talking to Dr. Steven Strange (Benedict Cumberbatch), who is at a crossroads: either return to his previous life as a superstar-conceited neurosurgeon, or use his newly acquired mystic powers to save the world.

Sometimes things seem to happen for a reason. Some people call these events happy coincidences, others call them the work of God, or of many gods, while yet others see them as manifestations of one's karma.

You read it everywhere, you watch it on TV and in sci-fi movies: Science is dangerous, it can create terrible weapons, it can control our lives, it can create new diseases, machines that will take over the world, that will wipe out the human race and redefine life as we know it.

Earlier this week, I visited a fourth-grade class at the public school where I live. I try to go every year to different classes, from grade school to high school, to tell students about the universe.

The class had been studying the solar system, in particular the planets and their properties. The teacher gave me carte blanche to do whatever I wanted. I felt that contextualizing planets would be a good idea, telling their story from birth to death, their relation to their parent star, in our case, to the sun.

Being in Kaikoura, New Zealand, for what is allegedly the first astrobiology workshop here, it's a good time to go back to the basics and reflect on what we know of the complicated question of the origin of life on Earth — and the possibility of life elsewhere.

I will do this, here at 13.7, in installments during the next few weeks.

One of the indisputable advantages of the Internet is accessibility of information, in particular for educational purposes, inside and outside schools.

Vast collections of what we photograph, study and catalogue are available by typing a few words and clicking on a few tabs. For someone who grew up scavenging local libraries to retrieve what little information was available, this accessibility is nothing short of a revolution — and an amazing one.

The origin of the universe is one of the most difficult realities we ponder.

It bends our logic, straining the words we have to describe it. If one is to say the universe started at the Big Bang some 13.8 billion years ago, the immediate reaction is: "But what came before that? What caused the Big Bang?"

This is the issue of the "first cause" — the cause at the beginning of the causal chain that caused all else but was itself not caused — that has plagued and inspired philosophers for millennia.

We learned Tuesday that Takaaki Kajita, from the Super-Kamiokande Collaboration in Japan, and Arthur McDonald, from the Sudbury Neutrino Observatory Collaboration in Canada (SNO), won the 2015 Nobel Prize in physics for helping to solve a long-standing mystery in physics: the disappearing neutrinos.

First, we had the mindboggling announcement that there is strong evidence of liquid water flowing on the Martian surface. And, also this week, on Oct. 2, the much-awaited Riddley Scott movie, The Martian -- based on Andy Weir's novel and starring Matt Damon as an astronaut stranded on Mars — opens nationwide. It seems that the red planet won't play second fiddle to the moon, especially a blood red one.

On Thursday, the Boston Museum of Science will premiere The Hidden Code at the Charles Hayden Planetarium, a multimedia piece by Paul Miller (aka D J Spooky). The piece combines music, stunning visual effects and live readings to bring science to the general public in ways that only a few years ago would be unthinkable.

Last Saturday, two-time Pulitzer prize winner Amy Harmon published a fascinating article in TheNew York Times about a young dying woman who chose to have her brain preserved in case neuroscience could one day restore her mind back to life.

Few questions of our time are more perplexing than the transition from non-living to living matter.

How did a sample of inorganic chemicals self-organize to become a living creature, capable of absorbing energy from the environment and reproducing? Although the question remains open, there are a few things that we can say based on present-day knowledge.
